T all whom, it may concern:

Be it known that we, WILLIAM CHARLES SMITH, loom-tuner and mechanic, residing at No. 13 Dudley Street, and JOHN BARLOW, en-

gineer, residing at 1 Yew Tree Road, Kidderminster, W'orcestershire, England, subjects of the Queen of Great Britain, have invented certain new and useful Lmprovements in Looms for Weaving Pile and other Figured ro Fabrics, (for which we have received Letters Patent in Great Britain No. 7,090, dated April 13, 1892,) of which the following is a specification.

Our invention has for its object the manu- 15 facture of Brussels carpets and other figured fabrics without the ordinary jacquard.

Our invention consists in an improved and simplified apparatus for selecting the warp threads and separating them to form two zo sheds, an upper shed for the pile wire and an under shed for the shuttle.

In carrying out this invention we substitute for the cords in the harness, wires with eyes in them, through which the figure warps pass and thence to the reed or sley. These harness wires are acted upon from below by the cylinder and cards of the pattern to produce the sheds to receive the pile wire and the shuttle. The harness wires may be supported in position by hooks, formed on them, resting on bars or plates with holes through, or in any convenient manner. This arrangement may be made available for raising the whole of the ligure warps in the Brussels loom 3 5 for the weft to go on the back of the carpet.

In order that our invention may be properly understood and carried into effect we will now proceed to particularly describe the same by referring to the accompanying drawings.

Figure 1 is a front elevation of a Brussels carpet loom with our invention applied, certain well known portions of the loom being omitted so as to show our invention more clearly. Fig. 2 is a side elevation of part of the mechanism. Figs. 3 and l are side sectionalv elevations of the loom showing the parts in different positions as hereinafter described. Figs. 5 and 6 show on-an enlarged scale and in different positions the lower parts 5o of the harness wires and the cylinder and cards in cross section. Fig. 7 shows the cylinder separately in side view and Fig. 7 X shows the same in end view. Fig. 8 shows separately in elevation and Fig. 8X in plan the part by which the harness wires are suspended; and Fig. 9 shows in side elevation and Fig. 9 in front elevation oneof the harness wires separately.

The wires which we substitute for the cords in the harness are marked A. 6o

The particular loom shown upon our d rawings is for weaving a narrow stuff.

The wires are arranged in three rows and it is to be understood that we use any number of these wires which may be required each 6 5 wire being a substitute for one of the usual harness cords.

Each of the harness wires A is hooked at the top ct and is thereby suspended from the bars of the cross board B which is fixed to 7o the two vertical side rods O O2. These rods are supported by and can move up and down in bearings in the upper and lower cross plates D and E. The upper cross plate D is fixed by the pillars F F2 to the side frames G G2( 75 of the loom and the lower cross plate E is also fixed to these two side frames.

H is the pattern or Jacquard cylinder and l the pattern cards arranged to move vertically up and down together below the bottom 8o ends d2 of the harness Wires A.

The vertical up and down movement of the pattern cylinder H and cards I is obtained by the cylinder ends h h2 being carried in bearings in the outer ends of the two side levers J J2 between which the cylinder H is located. These side levers turn about the fixed shaft K as a fulcrum and are raised and lowered at the proper times by the two cams L L2 fixed on the revolving shaft Z 9o and acting on the rollers j on the levers J J2. v

In order to cause the cylinder H to keep in a vertical line as it moves up and down the levers J J2 are slotted at 3'2 so as to be 95 free to move to and fro about the fulcrum K and the levers are prolonged beyond the shaft K and slotted at js to the peculiar form shown vin Figs. 3 and 4. As the levers J J2 move up and down these slots L7'3 acting in conjuncroo tion with the fixed and stationary bar t7'4 passing through them move the levers J f J 2 endwise to such an extent as to /keep the cylinder H in a vertical line. The shaft Z is driven from the usual crank shaft M by the spur wheels Z2`m2 so as to revolve at halt the speed of the shaft M.

The harness wires A are kept the proper distances apart by the cross board B and by the holes in the lower cross plate E.

Each of the harness wires A has an eye a3 through which one of the figure warps n n2 is passed as stated above.

In each side of the cylinder H there are holes corresponding with the harness wires A, and in the cards I there are holes corresponding with the wires of the ligure warps which in the various stitches do not have to come to the top.

To form the sheds for the draw wires or pile wires and shuttle the cylinder H is as above described moved upwardly and the cards I act upon and lift the harness wires A carrying the iigure wai-ps n which are to form the top shed. The other harness wires pass through the card I and the cylinder H and then carry their ligure warps into the lower shed n2. The levers J J2 then in rising come in contact with the lower ends of the side rods C C2 and lift the same and the cross bar B and wires A into the top position (see Fig. 4) and those warps of the wires A which are lifted by the pattern card form the top shed n and the other warps of the wires A which passed through the card I and cylinder H form the lower shed n2. The linen warp is operated by harness and in the usual way. In the weaving the draw wires or pile wires areinserted between these two sheds n 'n.2 and the shuttle passes underneath them in the usual way.

To insure the wires A moving down with thel cylinder H to their lowest position shown by Figs. 1, 3 and 5, we provide above the harness wires A a sliding pusher O the ends of which are guided by the side rods C C2 to move up and down vertically. This pusher O is operated by the cam o on the shaft Z acting through the'lever 02, connecting rod osand top lever o4 which latter is jointed to the upper end of the stem o5 of the pusher O. When the cylinder H and cards are falling the pusher moves down on to the upper ends of the harness wires A and pushes them down into their lowest position. The side rods C C2 and cross bar B, with the harness wires A, are supported in their lowest position by the nuts q q on the tops of the side rods C C2 resting on the top of the upper cross piece D.

The so called card cylinder H is not strictly speaking a cylinder but we have called it a cylinder as that is the name 'usually given to it by weavers. We find the square shaped cylinder shown on our drawings answers well in practice.

Various means may be adopted for turning the cylinderH to bring the next card and side of the cylinder to the top ready to act upon the harness wires for the next throw of the shuttle. The mechanism for this purpose which we show in Figs. l, 3 and 4 we have found to answer well in practice. The mechanism consists of an arm p fixed to the slide p2 which is carried in the bearing p3 and is jointed at p4 to the lever p5 which lever is jointed to the loom frame at p6. A roller p7 on the lever p5 is'acted upon by the cam p8 on the shaft Z so that when the cylinder H is in its lowest position the cam los moves the lever p5, slide p2 and arm p from left to right and the top of the arm p catches one of the ratchet teeth h3 on the cylinder Hand turns the cylinder H far enough to bring the next side of the cylinder and card to the top. The cylinder is held in this position by the usual spring slide q (Fig. l) carried by the arm J 2 actin upon the bottom side of the cylinder.

It will be understood that we have only shown a few of the cards upon our drawings, and that the cards after coming into use pass down to the usual appliances for holding the cards but with our invention as above described these appliances are arranged below the loom instead of being up above as is the case when the ordinary jacquard is used. The cards can thus be more readily got at and the weavers time' is saved. Moreover with our invention as above described the wear and tear of the working parts are much less than with an ordinary jacquard as we have no cards to wear and to renew and there is a much smaller from the jacquard.

l. In looms for weaving` Brussels carpets and other figured fabrics, the mechanism for selecting and lifting the figure warps to form the pattern, consisting of the combination of the vertical harness wires a, having hooks a', v

at their upper ends,'and eyes CL3 to carry the warp threads, the cross-board B, with the bars having openings between them through which both the wires and their hooked ends extend, the Jacquard cylinder H, the pattern cards I, and mechanism for lifting the Jacquard cylinder and presenting the cards to the lower ends a2 of the harness wires.

2. The combination of the vertical harness wires a; the cross board B engaging the wires a; the Jacquard cylinder H; the pattern cards I; mechanism for lifting the Jacquard cylinder; and for lifting the cross board B, thereby producing two sheds the one to receive the pile wire and the other for the passage of the shuttle.

3. The combination of the vertical harness wires a; the Jacquard cylinder H; the pattern cards I; mechanism for lifting the Jacquard cylinder and presenting the cards to the lower ends of the harness wires; a pusher O and mechanism for lowering the pusher against the upper ends of the harness wires. j

4. The mechanism for lifting the Jacquard percentage of flights yarns than is the case with ordinary cylinder H up to the lower'ends of the harp ness wires; consisting of the levers J J 2 provided With slots L7'2 and js; the fulcrum bar K; the guiding bar 3'4 and the cams L L?.

5. The mechanism for lifting the Jacquard cylinder H and also the cross board B to form a double shed; consisting of the levers J J 2 provided with slots c7'2 and js; the fulcruxn har K, the guiding bar ji; the side rods C C? on the cross board; and the cams L L2 which lift the levers J J2 and cause them also to io thrust up the side rods and the cross bar.
